FASTENING AND ATTACHING DEVICE FOR BROOCHES, JEWELRY, &c.

SPECIFICATION forming part of Letters Patent No. 533,008, dated. January22, 1895. Application led September y.18, 1894. Serial No. 523,381- (Nomodel.) Patented in England January 21, 1894,'No. 1,458'.

.To @ZZ whom itmay concern:

Be it known that I, THOMAS GRAINGER, a subject of the Queen of GreatBritain, residing at Hobart, in' the Colony of Tasmania, have inventednew and useful Improvements jin Fastening and Attaching 'Devices forBrooches, Jewelry, and the Like, (for which I have received LettersPatent in Great Britain the 21st day of January, 1894, No. 1,458,) ofwhich the following is a specification.

This invention relates to a new or improved means or method forattaching and fastening brooches, jewelry, and the like ornaments todresses and other articles of wearing apparel, such as cloaks, mantles,bonnet strings, collars, and the like, all of which are hereinaftertermed dresses, and `it may also be employed for pinning on or fasteningportions ofv such garments together.` Hitherto in brooches as at presentconstructed, the pin or fastening device is hinged at one end to theback of the brooch, while the opposite and pointed end of the pin ismade to pass through the garment and it is held by a catch or hook. Thismethod of fastening and attaching the brooch to the garmentis veryliable to get out of order by the pin becoming strained or broken off atthe hinge, thereby rendering the brooch useless until a newv'pin isattached thereto.

According to this invention the pin for fastening the brooch or otherpiece of jewelry or ornament, hereinafter termed brooch, is made so asto be detachable from the main portion of the brooch. f

It consists of a straight pin provided with a head and armed with afixed collet or collar arranged at a suitable distance from the head ofthe pin. Between the fixed collet and the head of the pin is mounted, onthe pin, a sliding bolt, preferably, though not necessarily so, of twodiameters, arranged to engage with a hooked and slotted bracket fixed tothe back of the brooch for connecting and fastening the two pieces, thatis, brooch and pin, together. The sliding bolt is retained in connectionwith the slotted and hooked bracket by means of a helical spring. Thepointed end of the pin is arranged to be passed into and held by asecond slotted bracket which forms a catch.

In the drawings hereunto annexed, Figure lis an elevation, Fig. 2 an endelevation,and Fig. 3 a plan of the pin and means for attaching andfastening it to the brooch; Fig. 4, an enlarged part sectionalelevation, and Fig. 5 an enlarged end elevation of detachable pin. Figs.6, 7, and 8 are, respectively, a sectional elevation, and back and frontelevations of the hooked slotted bracket; Fig. 9, an enlarged elevationof bracket for receiving the pointed portion of the 'detachable pin.Fig. l0 shows the application of the slotted brackets directly to theback of a brooch.

A is the detachable pin, which may consist of a piece of `steel or otherwire pointed at the end a, and provided withhead a' and armed with acollet or collar B (hereinafter. termed collet) fixed at a suitabledistance from the head of the pin. 0n the pin A is mounted, between thehead a and the collet B, a sliding bolt C. The periphery of the bolt Cis preferably made of three diameters, not necessarily so, C, c,.c, asshown at Fig. et. The bolt C is bored with a hole of two diameters c2,c3, to form a recess and a shoulder for receiving the end of ahelicalspring D, which is mounted on the pin between the head and the internalshoulder portion of the bolt C. The smaller diameter c2 of the hole inthe bolt is of such a size as to slide freely upon the pin A.

E is the slotted bracket for receiving the reduced end c of the bolt C.The bracket E is provided with a hook e projecting from itsfrontport-ion as shown at Fig. 6, for receiving the collet B as shown atFig. 1. In the bracket E is formed a hole of two diameters, e', e2, thelarger one of which is arranged to pass from the back of the bracket tonear its front portion as shown at Fig. 6. The hole e forms a recess forreceiving the reduced end c of the sliding bolt C, while the diameter ofthe hole c2 is such that the pin A may freely pass into it. The bracketE is also slotted as shown at e4 (Figs. 7 and 8) 4for allowing thepinAto be readily passed into or withdrawn from the 4I do not limitmyself to this or any other particular method of producing the saidbrack- 'Ioo I end of the pin A and it is provided at its upper end witha holef, suitable to receive the pointed end of the said pin A, and aslot f. The slot f is of such a size at the point at which it joins thehole f that onlythe pointed portion of the pin will pass through it. By

. this means a catch is formed for the small end of the pin.

The brackets E, and F may either be fixed directly to the, back of thebrooch as shown at Fig. l0, or they may be cast onor fixed to a backing'piece or stretcher G, as shown in Figs. 1 to 3.

The mode of attaching the brooch to a dress or other article of wearingapparel is as follows: The pin A is first detached from the brooch andis then passed through the dress or portions thereof into the positionin which it is to be worn. The pointed end a of the pin is then insertedwithin the hole f of the catch bracket F until the collet B is in aposition to be passed down at the front edge of the bracket E forengaging with the hook e. The sliding bolt C is then withdrawn in thedirection of arrow, from the position shown at Fig. 4, and in so doingits reduced end c slides upon the inclined surface e3 of the bracket E.When the sliding bolt C has been withdrawn sufficiently far to permit ofthe outerend of the reduced part c to be clear of the bracket, the pin Acan then be pressed down slot e4 to the position shown at Fig. l. Afterwhich, on the sliding bolt C being released, it will be returned by theexpansion of spring D, until the reduced end c passes within the recesse of bracket E 'for firmly attaching the pin and brooch together and forfastening the latter in position.

To unfasten the brooch and disconnect it from the pin may be readilyaccomplished by withdrawing the reduced end c of the slid ing bolt Cfrom its engagement with the bracket E.' g

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I-declare thatwhatI claim isl. In a fastening for brooches, the combination of apointed pin armed with a head and a collet fixed at a distancetherefrom, a sliding bolt mounted on said pin between the head of thepin and the fixed collet, and a spring mounted on thevpin, andinterposed between the head and the rear end of the sliding bolt, as setforth.

2. In a fastening for brooches, the combination with the back of abrooch of a detachable pin armed with a head and a fixed collet at adistance therefrom, a-bolt sliding on the pin between the fixed head andcollet, and a spring encircling the pin and interposed be` tween thefixed head of the pin, and a recess in the sliding bolt, as and for thepurposes set forth.

3. In a fastening for brooches, the combination of la brooch armed atits back with two slotted and recessed brackets, one of said bracketsbeing also armed with a hook for receiving a collet fixed to adetachable and pointed pin armed with a fixed head and having a boltsliding on it between the head and the collet, as set forth.

4:. In a fasteningV for brooches, the combination of a brooch armed atits back with slotted brackets for receiving and holding a detachablepin, said pin being armed with a fixed head and a collet fixed-at adistance therefrom, a bolt reduced` at one end to fit one of saidbrackets and sliding on said pin between the head and fixed collet, anda spring
